Oil/Water Separators

Different by being better — simple, elegant design with no moving parts, covering 75 cfm to 7,000 cfm.

Design Philosophy

Easy to install. Totally reliable.

STELSEP separators feature an elegant, simple design — no gravity pre-separation stage, no separate oil container to empty, and no moving parts or adjustments. Special filter media handles the separation reliably and efficiently.

Lightweight, dust-free filters — twice as long-lasting as activated carbon alternatives
No gravity pre-separation required — a simpler, more compact installation
Minimal floor space — wall or floor mountable across the range
Quick, easy servicing — cartridge-type packs, no mess, no specialist tools

Special Solutions

Emulsified Condensate?

Some compressors — typically those using synthetic lubricants or operating at high humidity — produce emulsified condensate that standard media cannot adequately treat. STELSEP has a solution.

Normal condensate — standard separator handles this effectively

AF Upgrade Available

Where emulsified condensate is an issue, STELSEP offers an AF (anti-foam / anti-emulsion) upgrade for the separator range — contact us to discuss your specific application.
